How to serialize objects that contain a foreign key object

[Ariel]

I need to serialize a an object that has a foreign key object for example:
I have this model:

class Town(models.Model):
    name = models.CharField(max_length=50)
    extension = models.IntegerPositiveField()

class Restaurant(models.Model):
    hot_dogs = models.BooleanField()
    town = models.ForeignKey(Town)


from django.core import serializers

json_serializer  = serializers.get_serializer("json")
data = json_serializer.serialize(Restaurant.objects.alI(), ensure_ascii=False)

But problem is that when the list of restaurant objects are serialized only the primary key of the town object is serialized but not the name and the extension, this is what I get:
[ {pk : '1', hot_dogs: 'True' , town: '1'}, {pk : '2', hot_dogs: 'False' , town: '1'}, {pk : '3', hot_dogs: 'True' , town: '2'} ]

And I would want to get the name and the extension of the town foreign key object too.
I hope you can help me

Thanks in advance.

Django 1.2 comes with a parameter [1] at serializers that do this for
you.

Unfortunately no. We didn't mark appropiately that documentation section
as a new 1.2 feature. I've opened ticket [1]#12840 for that.

For your original problem, you might want to try the external
project [2]'Django full serializers' by Matthew Flanagan.
